retired rick arnold knew it would be a high profile case. he did not know it would be the case of a lifetime. this is detective rick arn d arnold. today is may 18th, 2006. the video camera rolled across the crime scene. this is where the victim s body was located. the harsh reality of death lay side by side with the images of young life. erin s body in a pool of brood near a red kid wagon. a shell casing in front of a box of diapers. and the bed where erica jumped for joy was cases. detective arnold noticed something on the bed that would burn in his memory throughout the investigation. the first thing that immediately hit me was the dora the explorer pillow. it had blood on it. what was the emotion when you saw that?
